Description
Technical field
The present invention relates to a kind of piston, specifically a kind of air compressor piston.
Background technique
Air compressor is a kind of equipment to compressed gas.Air compressor is similar with water pump structure.Most of skies
Air compressor is reciprocating-piston, rotating vane or rotary screw.Centrifugal compressor is very big application program compressor
When work, air is inhaled by self-cleaning air filter, and by PLC automatic cleaning strainer, air is led by import
Enter one stage of compression after leaf automatic adjustment, the gas temperature after one stage of compression is higher, carries out subsequently into intercooler cold
But enter two-stage compression system after (water is walked in pipe, is made leave with rage outside pipe, and the water flow of intercooler requires to be 110m/h), to avoid being
Gas in system, which pours into compression chamber and (avoids starting with pressure) exhaust pipe in compressor and is equipped with a suspension complete opening type, to be stopped
Valve is returned, the gas of compressor discharge pushes check-valves open and enters exhaust silencer, subsequently into level-one aftercooler, second level aftercooler,
Enter back into exhaust manifold road.
Traditional piston is to be formed by silico-aluminum die casting, with the circumferential groove in its end portion for inlaying oil ring and compression ring.By with even
Bar shares piston pin and links together, and opposite within the scope of certain angle can swing therebetween.
It can generally be arranged with rubber ring in piston, to increase the leakproofness of piston and casing wall, however using a timing
Between after rubber ring on piston there are certain losses, and then cause the leakproofness of piston and casing wall poor, piston cylinder caused to use
Effect is poor.
Summary of the invention
The purpose of the present invention is to provide a kind of air compressor pistons, to solve the problems mentioned in the above background technology.
